This Guard Column contains 3 Pk.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Diol Supelguard Cartridge, 5 μm Particle Size
LC-Diol columns can be used to separate proteins by gel filtration chromatography.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-DP Supelguard Cartridge, 5 μm Particle Size
Contains a diphenyl bonded phase, which gives greater selectivity for aromatic groups compared to alkyl-type bonded phases.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-CN Supelguard Cartridge Kit, 5 μm Particle Size
The LC-CN phase is often used as a substitute for silica because it offers the advantages of a bonded phase (such as quick equilibration, and less sensitivity to small changes of the water content in the mobile phase).
